To all whom it may concern:

Be it known that I, RALPH H. SHERLOCK, a .citizen of the United States, residing at Riverside, in the county of Cook and State of Illinois, have invented new -and.useful Improvements in Tobacco-Pipes, of which the following is a specication.

This invention relates `to tobaccoipes of the type embodying a stem, a bow and a chambered body portion' for receiving and connecting said parts, and has for its objects to produce a comparatively, simple inexpensive device of this character wherein the accumulation of nicotin or moisture in the stem or bowl is obviated, one in whichI the bowl will be securely retainedI in the body, but

, may be freely removed therefrom, and one in Y which the moisture in the stem will at all times flow away from the ti of the latter, thus to obviate its entrance into the mouth of the smoker.'

With these and other; objects in view the I invention comprises the novel features of construction and combination of parts more fully -hereinafter described.

In the accompanyin drawings, Figure 1 is a section taken centrally and longitudinally through a pipe embodying the invention. Fig. 2 is a perspective view ofthe pipe, showing the inner bowl and clamping member detachedand the bowl in section.

Referring to the drawings, it will be seen that the improved pipe comprises an outer bowl or body portion 1, an inner bowl 2, and a stem 3, the body 1 being provided with a nicotin-chamber 4, which receives the bowl 2, and with a saliva-chamber v5, in which is l tted one end of the stem 3, while leading from the chamber 4 is an opening or Ipassa eway 6, through the medium,y of w ich te chambers communcateone with the other.

The bowl 2, which seats within the chamberv adjacent upper edgeof the body, and with a marginal portion or flange 9, which fits tightl in and for closinfg the mouth of the cham er 4, thel internal iameter of which is somewhat greater than the external'diameter of the bowl, thus to form a smoke-s ace 10 around the latter when seated in p ace,

there being formed in the outer faceI of the `bowl immediately -beneath the portion orV 'flange 9 a peripheral groove or depression 11, ada ted to receive a split clamping-ring 12, equipped with outwardly-bowed depending spring-engaging portions or iingers `13,which in action bear between Vtheir ends withina groove or depression 14, formed marginally around the interior of the body 1 within the chamber 4. The stem 3, which is preferably of the form shown, is provided, as usual, with a smoke passage or'bore r15 and is formed to lit tightly at its lower end in the chamber 5 and to terminate short of the bottom of the` latter and at a point above the adjacent end ofthe by-pass 6, it being noted that the bore 15 is considerably enlarged at the lower end of the stem, as at 16, to permit r'ree entrance of the smoke into the stem and is pitched upl wardly at the outer end of the stem, as at 17, thus to prevent moisturewhich condenses in thestern from passing into the mouth of the smoker.

- In practice the smoke passes from the bowl 2 through the chamber 4 and by-pass 6 to the chamber'5 and thence through the stem, as usual, it bein noted that the nicotin from the tobacco will be deposited in the chamber 4 beneath the bowl, while saliva flowin into the stem 3 will be deposited in the cham er 5, and, furthermore, that owing to the by-pass 6 being disposed at a point remote from the bottoms of the chambers 4 and 5 and at a downward inclination from the former to the latter the passa e of .nicotin into the chamber 5 is rendere practically impossible. It is to be observed that the bowl 2 will when seated be maintained securely in place by the clamping-fin ers 13, but may be readily removed, as wi l be understood, for purposes of cleaning the chamber 4, and, further, that owing to the provision of the depression 14 the action of the iingers 13 will be rendered effective, while at the same time their elasticity will to a measurablev extent be unimpaired and their life prolonged.

Having thus described my invention, what` I claim isy 1. A tobacco-pipe comprising a body portion having a nicotin.chamber,` a bowl ada ted to seat in said'chamber and provided with aan'ge to rest on the uper edge of the body, and a second flange to t within and close the mouth of the chamber, and a clamping-ring applied around the bowl and having s ringengaging portions adapted to bear ont e 1nner face of the body for holding the bowl in place.

`IOC) IIO 2. A tobacco-p pe comprising a body por- 1 chamber for removably retaining the bowl ro tion havin a niootin-ellamber, a bowl adapttherein. ed to Seat 1n said Chamber and provided With In testimony whereof I affix my signature a flange to rest on the upper edge of the bodT in presence of two Witnesses. and a second flange to fit Within and close the mouth of the chamber, the bowl being also RALPH H' SHERLGCK provided with a groove, a ring disposed in Witnesses:

said groove and having spring-enga ing fin- EDWARD W. HATCH, gers adapted to engage the inner Wal of the HAROLD G. FERRIS.
